There’s a huge catalogue of free, battle-tested command-line tools in the Linux world — for images, PDFs, video, text, and almost any file you can name. The old way to use them on Windows was to spin up a full virtual machine: download an ISO, size a disk, install a desktop you didn’t want, and shuffle files back and forth. That’s a lot of overhead to run one converter.
WSL removes all of it. You get a real Linux environment that installs tools with apt, works directly on your Windows files, and runs from a terminal next to your normal apps — no VM to build or maintain. This guide explains how that fits together so the individual task guides make sense.
If you haven’t set it up, our WSL install guide is the one-command starting point.
”Without a VM” — what that actually means
WSL2 does use a lightweight utility VM internally, but you never touch it the way you would VirtualBox or Hyper-V. There’s no virtual disk to provision, no guest desktop, no network bridge to configure. Microsoft manages that layer for you. From your side it’s just a terminal: open it, run a Linux command, done.
That’s the practical difference. A traditional VM is a separate computer you operate. WSL is Linux tooling stitched into Windows, sharing your files and clipboard, idle until you actually run something.
Traditional VM vs WSL for running tools
| Setup | Install ISO, size disk, configure |
|---|---|
| Your Windows files | Copy in/out or share a folder |
| Resource use | Reserved while running |
| Best for | Full separate OS, GUI apps |
Installing tools with apt
On Ubuntu (the default WSL distro) and Debian, software comes from apt. Refresh the package list once, then install whatever you need:
sudo apt update
sudo apt install -y ffmpeg imagemagick ghostscript poppler-utilsEach becomes a command you can run immediately. There’s nothing to download from random websites and no installers to click through — apt pulls vetted packages from the distro’s repositories.
Working on your Windows files
This is the part that makes WSL genuinely useful for everyday jobs: your Windows drives are mounted inside Linux under /mnt. Your C: drive is /mnt/c, so your Pictures folder is:
cd /mnt/c/Users/YourName/PicturesFrom there, any Linux tool operates on those files in place, writing output right beside them. No copying into the Linux environment first.
# example: convert every JPG here to WebP
for f in *.jpg; do cwebp -q 80 "$f" -o "${f%.jpg}.webp"; doneWhy local tools beat the web versions
Every task in this cluster could be done by some website. Running the tool yourself wins on the things that actually matter:
What you gain by running tools locally
- Privacy — files never leave your machine
- No upload or download step
- No size limits, daily caps, or queues
- No watermarks and no account
- Batch entire folders in one command
- Free, open-source, reproducible
For a contract, a folder of personal photos, or a long recording, that privacy point alone settles it. You’re not trusting an unknown server with files you’d rather keep to yourself.
The tools worth knowing
A handful of packages cover most everyday file work:
- FFmpeg — video and audio: compress, convert, extract audio, trim.
- ImageMagick — resize, convert, and compress images: batch resize.
- Ghostscript + Poppler + qpdf — PDFs: compress, merge, split.
- cwebp / ExifTool — WebP conversion and metadata removal.

Stopping WSL when you’re done
WSL sits idle when nothing is running, so it won’t slow Windows down in normal use. When you want it fully stopped — to free memory or get a clean restart — run this from PowerShell or Command Prompt:
wsl --shutdownIt starts again automatically the next time you open a WSL terminal.
Wrapping up
Running Linux command-line tools on Windows no longer means building and babysitting a virtual machine. WSL gives you the whole toolbox: install with apt, reach your Windows files under /mnt, run free tools that keep everything local, and shut it down with wsl --shutdown when you’re finished.
Once the model clicks, the individual guides are just specific commands on top of it. For a deeper look at the file bridge between the two systems, see access your Windows files from WSL.
